1 Claim.

My invention relates to appliances for transferring gasoline from tank-cars or storage receptacles to truck-tanks for transportation. And the objects of my invention are: first, to design and develop an appliance for said use that will be eflicient for said purpose and of such a character that it can be constructed at a reasonably low cost in material and workmanship. Another object of my invention is to provide for the delivery pipe an adequate counterbalance readily adjustable on a swinging arm, adapted to operate always on the side of an upright supporting pipe opposite said delivery-pipe. Another object of my new invention has been to design for said appliance a swing-joint whose rotary stem could be locked in its service position, as originally installed in the casing of the joint. Other objects of my invention will appear in the process of this specification.

The foregoing objects have all been attained in my present invention; and my new and useful device for loading gasoline into truck-tanks, illustrated in the accompanying drawing forming a part of this specification, is a practical device embodying the aforesaid novel means and other new and useful details of construction, arrangement and combination of parts, all of which together with their functions will be described in detail with reference to said drawing and will be definitely pointed out in the claim that follows this description, so that any person skilled in the art may be able to construct and use this invention.

In said drawing Fig. 1 is a top plan view of my improved device for loading gasoline into truck-tanks, showing the main delivery pipe and its heavy counterbalance in their relative service positions.

Fig. 2 is an elevational view of the side of my improved appliance for transferring gasoline from car-tanks or storage receptacles to trucktanks, showing in solid lines the main delivery pipe thereof in its normal service position, and in broken lines, the highest position of said delivery pipe and the lowest position of its counterbalance.

Fig. 3 is an elevational View of the back side of my improved gasoline-loading device, all parts thereof being in the same relative position as shown in Fig. 2.

Fig. 4is a side view, partly in section and partly in elevation, of my new elbow swing-joint, showing the new collar around the base of the rotary stem and the adjacent annular slot in the inner walls of the joint-casing, with babbitt-filling for locking the stem therein.

This invention hasbeen designed and practically developed in its details of construction for the desirable purpose of producing at a comparatively low cost an efficient appliance for transferring gasoline from car-tanks or storage receptacles into truck-tanks for transportation. And with said purpose and the special objects abovementioned, in view, I will describe my invention in detail, pointing out the new and useful features in the construction and arrangement of the individual parts and the combinations thereof, as illustrated in the drawing hereinabove described, in which similar letters and characters refer to similar parts throughout the several views.

In the invention and development of my new gasoline-loading appliance, I have thoroughly tested out every detail of the mechanism in a complete assemblage of the parts involved in a working model thereof; and I have found in their functions not only complete success, but a more efficient adaptability for loading and unloading gasoline under various local conditions of receiving and delivering said material, than I have found heretofore in the appliances used for said purpose.

In Fig. 1 I have shown in a top plan view my improved device for transferring gasoline into truck-tanks, including the conventional main delivery pipe I and its heavy counterbalance l in their relative service positions. Delivery pipe I is provided with the conventional quick-closing gate valve la and the vacuum release valve lb and the auxiliary extension pipe lc, as well as the ordinary suspension-cable 3 fastened tosaid delivery pipe in an attachment-loop id.

Now for my said improved device for loading gasoline into truck-tanks, I have designed a new elbow 3d, containing an improved vertical swingjoint 8 in its upper end for the attachment of the delivery pipe I, by means of the rotary stem 9 and the common elbow 9b, as shown in Figs. 1, 2 and 3; said improved elbow containing, also, my new horizontal swing-joint 8 in its lower end for the attachment of my said improved device to the vertical gasoline supply-pipe 2, by means of the rotary stem 9 and the coupling 2a, as shown in Figs. 2 and 3. This new elbow Ed is provided on its upper side with an integral, rectangular pillow-block 4, shown in vertical projection in Fig. 1 and in a side elevational view in Figs. 2 and 3; but in Fig. 4 the elbow 8d is shown partly in a side elevational View and partly in longitudinal section, with the integral, rectangular pillow-block 4 left off to show more clearly the internal detail of my improved swing-joint.

The pillow-block 4 is provided with a deep, vertically-disposed, rectangular mortise in its upper end for the purpose of receiving the lower end of a curved, rectangular shaft 5 adapted to support a hooded housing 6 for a sheave-wheel 60:; up over the front part of which runs the suspension cable 3, thence extending downward to an attachment-loop fixed in the counterbalance I operative on a vertically-swinging arm la at the back side of said loading device directly opposite the main delivery pipe I. The swinging arm Ia of the counterbalance i is anchored in a pintle-hinge lb between a pair of vertically-disposed, parallel webs, 4a, 4a, cast integral with the pillow-block 4.

The lower end of the shank of the sheavewheel housing 6 is provided with a deep rectangular mortise adapted to fit securely on over the upper end of the rectangular curved shaft 5 in such a manner as to set the cable-track of the sheave-wheel and the attachment-loop Id of the pipe I, in the same plane. The upper portion of the sheave-wheel housing 6 is a rain-proof hood 61) adapted to turn rain-water from the ball bearings of the sheave-wheel 6a.

In designing the counterbalance of my conventional delivery pipe I, I have been fully conscious of the fact that the gravity factor of said delivery pipe, moving as it does up and down and being at one time full of gasoline and at another time empty, must necessarily be a variable quantity. I have, consequently, designed the counterbalance thereof so that, in its normal operation, its gravity factor will also be a correspondingly variable quantity, being adapted to change its counteracting force on the delivery pipe automatically, as the delivery pipe I changes its gravity force in its up and down movement. For exa ple, when the delivery pipe I is in its normal orizontal position full of gasoline while debriefing gasolineirom the storage receptacle into the truck-tank, as shown in Fig. 2, the delivery pipe I is heaviest, and the counterbalance 1, being out on the outer end of its horizontal swinging arm la, is thus in a position to exert its greatest counteracting force on delivery pipe I, the predetermined weight of the counterbalance'I and the length of the swinging arm Ia,

7 being ample to hold the delivery pipe I in its it must be securely held up out of the way of in-coming trucks, in the position shown in the dotted lines in Fig. 2, securely anchored so that, regardless of wind and weather, it cannot possibly come down untilpulled down by the hand of the operator; for its suspension cable 3, as shown in dotted lines in Fig. 2, is pulling not against the gravity factorof the counterbalance "I, but is exerting its force against the still arm 1 a and its rigid pintle-hinge lb, disclosing a novel arrangement in design and operation, which amounts to a locking means to anchor the empty delivery pipe I on high completely out of the Way of in-coming trucks, until pulled down by the operator for service in filling his truck-tank.

Now, with reference to the conventional swingjoint in general use, we find, in case of unusual strain across the rotary stem 9 on one side thereof, said stem tilts up more or less from its seat on the inside abutment-shoulder 8b and begins leaking. And to prevent this bad condition in the structure of the swing-joint in service, I have designed, in the inner walls of the jointcasing at either end of the new elbow 8d, two broad annular slots, 8a, 8a, opposite each other, each extending part-way round the abutmentshoulder 82) parallel therewith. And around the base of the rotary stem 9, I have made an integral collar 9a. And in assembling these said parts of the swing-joint, we first place the stem 9 into the open end of joint-casing, arranging the stem in position shown in Fig. 4 with its collar 9a resting full upon the smooth shoulder 8b designed, in said joint-casing, as a secure abutment for the collared stem 9, 9a. We then pour molten babbitt I [I down into the space between the rotary collared stem 9, 9a, and the inner walls of said swing-joint casing, filling the two slots, 8a, 8a, and the space all round to a certain height above the stem-collar 9a, which securely locks the collared stem, 9, EM, in its original position of installation,resting, in severe service, fully upon the smooth abutment-shoulder 8b, as shown in Fig. 4. The remaining space between said rotary stem and the inner walls of the swing-joint casing, is filled with standard packing-rings II which are securely held in their service position by means of the bolted outer clamps 80, 8'0, shown in Figs. 1, 2 and 3.

Now, for an illustration of the operation of my new device for loading gasoline into trucktanks for transportation, we may suppose, for instance, that two trucks with tanks to be filled drive up on each side of an upright gasoline supply-pipe 2 provided with my new gasolineloading appliance installed thereon; and the main delivery-pipe I is resting in its highest position, as shown with the broken lines in Fig. 2. The driver of the first truck pulls down the delivery-pipe I, on the vertical, swing-joint 8 and swings said pipe, on the horizontal swing-joint 8, round to his tank; and after fitting the outer end of the auxiliary extension pipe I 0 into his tank, he opens the quick-closing valve Ia and fills his tank. He then closes the quick-closing gate valve Ia and the gasoline in the outer portion of the delivery tube 5 and I0 is allowed to flow out as the air flows in through the vacuumrelease valve H) in pipe I at the outer side of said quick-closing gate valve.

As said first driver pulled down the deliverypipe I and swung it round to his tank to take on his load of gasoline and while he was pushing said pipe up again out of his way, he had a good opportunity to feel the value and the convenience of the movable counterbalance i operative on a vertically-swinging arm la anchored in a pintlehinge lb installed in the webs, 4a, id, on the pillow-block and adapted to counterbalance the delivery-pipe I in any vertical position and to swing horizontally all the way around the upright supply-pipe 2. Consequently, the second driver of said trucks, coming up on the opposite side of said supply-pipe, can swing the deliverypipe I all the way round to his tank, raising and lowering the pipe easily because of the counterbalance I, which also swings around with the pipe always on the opposite side thereof. And, as the front attachment loop Id of the suspension-cable 3, on the delivery-pipe I and the sheave-wheel 6a and its =cable-track are all in -the same plane, and the counterbalance I K131058157 adjacent thereto, the counterbalancing functions of the heavy delivery-pipe are practically perfect. And the adjustable detent 3a fastened to the suspension cable 3 is adapted for limiting the upward movement of the delivery-pipe when desirable on certain occasions of particular service.

But in closing, I think I should add that, in this description of my new and useful improvements in a device for loading gasoline into trucktanks, as set forth in the foregoing specification, it should be well understood that the specific detail of the various parts of the instant embodiment of my present invention, as I have illustrated in the drawing thereof and fully described, are not to be considered as limitations in the construction of my new device; and that while keeping within the scope of my invention and claim, I may make desirable modifications in these details to facilitate quantity-production or to economize in the fabrication of the parts thereof, provided I keep within the spirit and scope of my invention and claim.

Now, having thus described the various features of my new invention, the detail construction, arrangement and combination of its parts, as well as their functions and the ways and means of assemblage, operation and application; those features and accessories of my new device for loading gasoline into truck-tanks for transportation, on which I desire Letters Patent granted to me, I have set forth specifically in the following claim:

In an appliance of the character described provided with a delivery pipe for transferring gasoline from car-tanks or storage receptacles into truck-tanks, an improved elbow adapted to connect the main parts of said appliance by means of a vertical swing-joint in one end of said elbow and a horizontal swing-joint in the other end thereof; an integral, rectangular pillow-block cast on the upper side of said elbow and provided with a deep, vertical, rectangular mortise in the upper portion thereof, adapted to support rigidly other parts of said appliance; a vertically disposed rectangular shaft whose upper end is slightly curved and whose lower end is designed to fit rigidly into said mortise to prevent racking and turning therein; a vertically disposed sheave-wheel installed in a hooded housing for protection from the weather, said housing being adapted to be rigidly installed for support on the upper end of said rectangular shaft to prevent turning thereon; a variable counterbalance for said delivery pipe, installed on the outer end of a vertically swinging arm pintle-hinged in a pair of parallel integral webs on the side of said pillow-block opposite said delivery pipe, said counterbalance being adapted to operate with an automatically variable gravityfactor corresponding to the variable gravityfactor of said delivery pipe and designed to balance said pipe in any vertical position and to anchor said pipe securely in its elevated position of rest; and a strong connective suspension cable running freely over said sheave-wheel, with the front end thereof attached to said delivery pipe and its back end attached to said counterbalance for the normal operation thereof.
